Redvision X-SERIES™ take toughness to another level
Vandal-resistance is the most common toughness rating for CCTV
products. It is, in fact, a measure of impact resistance, as defined in
European standard EN 62262. Products are issued with an IK rating, from
IK 00 denoting no impact protection, through to IK10, the maximum. An
IK10 product will resist an impact from a 5kg steel mass dropping or
swinging into it, from 500mm.
Redvision believes IK10 is not exacting enough. Paul Hucker, Managing
Director of Redvision, explains, “A camera might experience far greater
forces in real applications. In our own impact testing we swing a 14lb
(6.5Kg) sledge hammer, on a 2m handle, at the camera with great force a
number of times. The camera resists the impact and remains intact.
See impact test video.
“Despite our exceptional impact resistance, an X-SERIES™ camera was
damaged when a speeding vehicle hit the base of a CCTV column, with the
camera mounted on top. The impact force had been conducted up the
column, demonstrating how vital a high impact resistance is.
“Redvision believes impact resistance is only one of many factors
that define ruggedness. Weather resistance and an ability to function in
rain are vital. We have an IP67 moisture-ingress rating for outdoor
use, but more practically we have a wiper to clear rain and dirt from
the camera view. We also have IR or white light options for night-time
operation. Resistance to corrosive environments can also be important.
We offer marine and extra-marine finishes, which are 25 year-rated,
corrosion-resistance plated. Heat and the cold are significant in many
applications. We have tested our products extensively and offer an
operating temperature range of -25°C to 60°C. Our cameras are very
reliable, with a MTBF of seven years, backed by our factory servicing
The impact forces on cameras in some applications can be immense and
an IK10 rating is not enough. We urge our customers to think responsibly
about public safety when designing surveillance systems and consider
CCTV tower design, location and protection levels.
